Abstract

In order to strengthen wetland protection, regulations called "The National Wetland Protection Project (2002-2030)" were issued by China's central government. Among the projects, wetlands in the Sanjiang Plain were given priority for restoration and protection. In this study, remote sensing data obtained from 2000 to 2015 are adopted to evaluate the effectiveness of wetland protection project in the aspects of area and distribution, landscape patterns, ecosystem quality, and ecosystem services. The results showed that, since 2000, the area extend of wetlands is decreased by 2508.55 km ², the decrease rates of 2000-2010 and 2010-2015 are 209.40 km ²/year and 89.91 km ²/year, respectively. The mean size of wetland patches decreased first and increased then. Although wetland vegetation coverage decreased from 91.8% to 74.0%, the net primary productivity (NPP) and the waterfowl habitat supporting service are slightly increased.
